what does the # character represent in an AIX IBM shell command?

Also can you give an example of how to copy the contents of an AIX IBM file into a text file via a shell command?

# generally represents a comment
#!  however is called shebang and tells the script location of the interpreter
eg  #!/bin/ksh

if you want to copy file
cp filename newfilename


cat filename > newfilename

if you ran

# grep SYSTEM /etc/security/user > 123.txt within a shell, would it work, or would the # comment out the command?

or put another way would
grep SYSTEM /etc/security/user >123.txt

work / run ok?

On the shell, if you are hitting the enter/return key and you get #, I think you are talking about the prompt sign

You can change it if you say

PS1="> "

To change it to > if you like.

Yes, if you are putting # yourself, that would comment it and it would therefore not run.

grep SYSTEM /etc/security/user >123.txt   work/run
